sqlhadr-review skillA
sqlhadr-review is agent-read markdown (skill) from vanterx/mssql-performance-skills: Analyzes sys.dm_hadr_* DMV output to assess Always On Availability Group replica health, synchronization state, secondary lag, redo and log send queue sizes, and configuration gaps. Use this skill when an availability group is behaving unexpectedly, a secondary replica is lagging, data loss is a concern, a database appears stuck initializing after a failover, or you need a SQL-side snapshot of AG health to complement CLUSTER.LOG and ERRORLOG diagnostics. Applies 27 checks (H1–H28, with H21 retir.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# SQL Server Always On AG Health Review Skill ## Purpose Analyze output from the `sys.dm_hadr_*` DMV family to assess the health of one or more Always On Availability Groups. Applies 27 checks (H1–H28, with H21 retired and merged into `sqlag-review` F15 — see Category 4) across six categories: - **H1–H6** — Replica connectivity and role: detect disconnected replicas, resolving state, unhealthy synchronization health, replicas not synchronizing, last-connect errors, and failover mode mismatches - **H7–H11** — Data loss and recovery time: flag estimated data loss, excessive recovery time, secondary lag, redo queue buildup, and log send queue buildup - **H12–H16** — Throughput and performance: detect stalled redo rate, stalled log send rate, rate mismatch causing queue accumulation, multiple databases lagging on the same replica, and commit latency signals on sync-commit replicas - **H17–H22** — Configuration: async replica in unexpected position, no automatic failover replica, single-replica AG, missing listener, and automatic seeding in progress (H21 is retired — read-only routing absence is covered by `sqlag-review` F15) …

How to install
mdr add vanterx/mssql-performance-skills/sqlhadr-review@git:20260622.55f8c85mdr add vanterx/mssql-performance-skills/sqlhadr-review@sha256:f0f40b6aa0b3b7e2Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
